Security risks and encryption solutions for iOS apps

Security risks and encryption solutions for iOS apps
As the two most popular systems for developers, Android and Apple iOS systems have received much attention. For comparison between the two systems, especially for security of iOS apps, it has been a constant debate over the past few years. Android's openness makes it popular and at the same time comes with risks. The closeness of iOS makes developers highly constrained, but also ensures security. Therefore, users generally think that iOS apps are safer.
First, compare the two systems to see iOS application security
Android: the Android system is open, and applications can read SD global public directories. In other words, applications can read data from each other, you can read or modify the Data Location and format. Therefore, applications may generate a large amount of data intersection, and therefore there will be a lot of content to be called by mutual delegate, this explains why some users experience traffic spikes, spikes in costs, or installation of applications with viruses with hidden charges. IOS application security
IOS: the iOS system is a closed system. In the development of iOS application security, developers must follow Apple's developer protocol, applications developed without complying with the prescribed protocols will not pass the App Store review, so that developers must abide by certain protocols when developing applications, you are not authorized to operate any content not in the program directory. IOS application security
IOS app security risksFrom the above point of view, the application security of iOS is relative to that of Android, but is the application security of iOS really so secure? As we all know, Apple's App Store is strictly approved, but there are thousands of applications for review and submission every day, while the disguise of malware is getting better and better, it also allows some malware to enter the App Store from the cracks in the review. As far as Apple is concerned, the difficulties it faces are also very bad. IOS application security. According to a recent survey by a foreign security service provider, 100 of the top 87% paid iOS apps were cracked. In addition to free iOS application security cracking, more and more paid applications are cracked. The cracked application types include various types, including games, commerce, production, finance, social networking, entertainment, education, healthcare, etc. These paid applications were originally paid for download, and after being cracked, users can download them without paying. Internal purchase cracking, source code cracking, local data theft, local data theft, network security risks, and iOS app security risks are everywhere.
Security risks of iOS apps1. The internal-purchased cracking plug-in method (only jailbreak), The iTools tool replacement file method (usually archive cracking), the hacker artifact modification 2. The network security risk intercepts network requests, crack the communication protocol and simulate Client Login to forge user behavior, damage to user data 3. Application function PATCH cracking use FLEX patch software to dispatch return values to conduct PATCH cracking on the application 4. source code security risks reverse engineer the ipa using tools such as ida disassembly code, as a result, the logic and modification of the core code affect the security of iOS apps. How can we protect the security of iOS apps? It is understood that the mobile app security protection platform-love encryption, launched the security encryption technology for iOS apps. Next, let's take a look at the security encryption technology for iOS apps.
Security encryption technology for iOS apps1. encryption of local data to NSUserDefaults and sqlite files to protect accounts and key information 2. encryption of URL encoding to encrypt URLs in programs, prevent the URL from static analysis. 3. network transmission data encryption provides an encryption solution for the client to transmit data, effectively preventing interception through network interfaces to obtain data. 4. Method body, method Name advanced obfuscation is performed on the method names and method bodies of iOS application security programs to ensure that the source code is reversed and the Code cannot be parsed. 5. program structure mixed encryption disrupts the application logic structure, minimize source code readability
